Some places in New Zealand have a surcharge, but if people need carry bags they pay it anyway. The price of the plastic bag needs to be prohibitive if this is going to make any kind of difference to the amount of plastic bags entering the waste dumps.

I always reuse any and all plastic bags I get either for trash or for picking up presents left by the neighborhood dogs on the neutral ground or sidewalk. LOL
I also try to use the cloth bags sold by most food and variety stores. They hold more and are easier to carry than the plastic and paper bags.
PLEASE EVERYONE GO GREEN!

I can go down any street and find plastic bags everywhere. They are hanging in trees, blowing across the streets and stuck in fences. IF you MUST use one, RECYCLEI IT!!
I know I forget my cloth shopping bags sometimes but I ALWAYS recylce plastic.
Get it together!

Many years ago, the world was fine with paper grocery bags !! When plastic bags started being made, Governments should have intervened and ordered the companies to make these bags biodegradable !! So now, governments should make the plastic bag companies pay for the cleanup of their products !!! ALSO, the internet has many ideas to use up these bags -- (my friends and I stuff these bags into quick-sewn outside patio cushions, etc.) !!!!
